Definitions

  • the present invention relates to a valve for a fire fighting installation and, in particular, for a fire fighting installation operating with a high drive pressure of extinguishing liquid.
  • a high pressure in this context means a pressure within the range of about 30 bar to about 300 bar, whereas conventional low pressure installations have an operating pressure of about 5-10 bar.
  • the source for the extinguishing liquid preferably is at least one hydraulic accumulator connected to the outgoing line of the installation to which a number of automatically releasable spray heads are connected.
  • the object of the invention is to provide a new valve which is reliable without access to electric current and is of a simple structure and, thus, cheap.
  • the valve according to the invention is characterized by a housing, an inlet into the housing and connectable to a high-pressure extinguishing-liquid source, an outlet from the housing and connectable to an outgoing line, and a spindle which is movable in the housing between a standby position in which the spindle closes a connection in the housing from the inlet to the outlet, and an activated position in which the spindle opens the connection from the inlet to the outlet.
  • the housing has a channel, which connects the outlet to a liquid space that is under the influence of liquid pressure from a secondary liquid source with a lower pressure than said high pressure source.
  • the spindle is arranged to be under the influence of the force of a spring that acts in the opposite direction from the pressure influence in said liquid space on the spindle.
  • the pressure of the secondary liquid source and the force of said spring are mutually adapted in such a way that, when the secondary liquid source acts with full pressure on the spindle via said liquid space, the spindle is held in the standby position and, when the pressure of the secondary liquid source has decreased to a predeterminable value due to liquid delivery to a released spray head, the spring drives the spindle to the activated position.
  • a nonreturn valve is preferably positioned in the channel of the valve housing. In the activated state, the valve prevents the pressure of the high pressure source from entering said liquid space.
  • FIG. 1 is an elevational view, partly in cross section, showing a valve in a standby state.
  • FIG. 2 is an elevational view, partly in cross section, showing the valve in an activated state.
  • a hydraulic accumulator 1 with a high charge pressure (e.g., 200 bar) is called in the following the primary accumulator. It has an outlet tube 2 which, preferably, is provided with a number of apertures in its wall in order to deliver first liquid and then a mixture of liquid and the drive gas of the accumulator as described in Finnish patent application Ser. No. 924752.
  • a valve housing 3 has an inlet 4 connected to the tube 2 and an outlet 5.
  • the outlet 5 is connected to an outgoing line 6 having a number of automatically releasable spray heads, only one being shown in the drawing.
  • the valve spindle 7 has a channel 8 starting from the inlet 4 and leading to an annular space 9 axially between the spindle and the surrounding valve housing.
  • the cross-sectional area of an end face of a piston-like part 10 of the spindle 7 in the annular space 9 is equal to that of the part of the spindle 7 at the inlet 4, which is under the influence of the pressure of the hydraulic accumulator 1.
  • the pressure action of the primary accumulator 1 on the spindle 7 is thus reversed (i.e., compensated or balanced) by the pressure action in the annular space 9 in the opposite direction against the end face of the piston-like part 10 of the spindle.
  • the pressure in the primary accumulator 1 thus cannot move the spindle 7.
  • An opposite end portion 11 of the spindle is axially movable through a fixed support element 12 of the valve housing in sealed gliding contact.
  • a helical spring 13 is laid around the spindle 7 and is supported at one end at inlet 4 and on the opposite end against the piston-like part 10 of the spindle. The spring 13 thus tries to move the spindle 7 upwards in FIG. 1 from the standby position in which the spindle keeps the connection from the inlet 4 to the outlet 5 closed.
  • the valve housing 3 has a channel 14, which connects the outlet 5 to a liquid space 15.
  • the liquid space is connected to a small (e.g., about 0.3 liter) hydraulic accumulator 16 with a low charge pressure (e.g., 6-10 bar).
  • the hydraulic accumulator 16 is called in the following the secondary accumulator.
  • the end portion 11 of the valve spindle 7 at least lies against one side of a head 17.
  • the head 17 is movable in the liquid space 15 like a piston between the position in FIG. 1, in which the one side of the head 17 presses against the fixed support element 12 of the valve housing 3 and the spindle 7 closes the connection from the inlet 4 to the outlet 5, and the position in FIG. 2, in which the opposite side of head 17 presses against a stop 18 of the valve housing 3 and the spindle 7 opens the connection from the inlet 4 to the outlet 5.
  • the spindle 7 is kept in the place shown by the pressure in the liquid space 15, which acts on the spindle head 17.
  • the spring 13 acts in the opposite direction, while the high pressure in the primary accumulator 1, as earlier mentioned, does not drive the spindle 7.
  • a nonreturn valve 19 in the channel 14 prevents the pressure of the primary accumulator 1 from entering the liquid space 15 when the spindle 7 is in the position shown in FIG. 2.
  • a manually operable pressure-release means 20 is in a closed position in FIG. 1 and an opened position in FIG. 2.
  • the invention can of course be applied to any number of hydraulic accumulators and/or high pressure pumps.
  • spray heads, nozzles, group release, and other arrangements these can be as described, e.g., in the International Patent Applications PCT/FI92/00060, . . . /00122, . . . /00155, . . . /00156, . . . /00193, . . . /00213, . . . /00316, . . . /00317, and . . .
